Definitions

  • the present invention relates to a caster, and especially to a caster provided with an oscillation preventing mechanism for restricting the oscillatory motion of a caster wheel.
  • the object of the present invention is to provide a caster capable of preventing the oscillating and turning motion of a caster body, which permits the free rotation of the caster wheel per se with a shock-absorbing effect, even while the oscillating and turning mortion is prevented.
  • An object of the present invention is to eliminate the above-mentioned drawbacks of conventional casters and to provide an improved caster having a high utility.
  • FIG. 1 shows an embodiment of the caster of the present invention
  • FIG. 2 is a partially sectional view of the caster of FIG. 1;
  • FIG. 3 is a front view of the caster
  • FIG. 4 is an exploded perspective view of the caster of the present invention.
  • the caster of the present invention is composed of a caster body 2 supporting a wheel 1, a caster holder 3 and a lock clip 4.
  • the caster body 2 is composed of a base frame 22 having a rotational axle 21 and an oscillating frame 23 mounted with a rubber damper 24.
  • the base frame 22 is connected to the oscillating frame 23 via an axle 25 so as to be freely movable.
  • a supporting axle 11 for the wheel 1 is mounted at the lower portion of the oscillating frame 23.
  • the caster holder 3 is made of synthetic resin or the like, and has a configuration sucn that a through hole 32 is provided in the base rod 31 and such that a recess portion 33 for receiving the lock clip is formed on the peripheral surface of the base rod 31 along the longitudinal direction thereof.
  • Numeral 34 designates an insertion hole formed on the top surface of the base rod 31 for receiving a supporting leg, but this means may be replaced by a dish-like fixing member (not shown) as usually used in a conventional caster.
  • the lock clip 4 has a configuration such that a pair of pinching plates 43 are mounted at the upper portion of a back plate 42, and a pair of base plates 41 are mounted at the lower portion of the back plate 42.
  • the base plates 41 are inserted into the base frame 22, and are rotatably mounted at the end portions thereof to the base frame 22 using the axle 25.
  • the lock clip 4 thus constructed may be made of metallic material.
  • the pinching plates 43 are composed of two resilient arm plates opposed to each other, and the end portions of the pinching plates 43 can pinch the recess portion 33 formed on the base rod 31 of the caster holder 3.
  • the topmost end of the back plate 42 is bent slightly outwardly so as to facilitate movement of the lock clip 4.
  • the caster body 2 can be freely oscillated and turned around the rotational axle 21 inserted into the caster holder 3, to thereby achieve the same effect as a conventional caster.
  • the caster body 2 is fixed to the caster holder 3 as a body, to thereby stop the oscillating and turning motions of the caster body 2 and to effect movement in a constant direction.
  • the caster body 2 is composed of a base frame having a rotational axle 21 and an oscillating frame 23 having a damper rubber 24, and since the base frame 22 and the oscillating frame 23 are movably combined by means of the axle 25, a shock-absorbing effect is always applied to the wheel 1, to thereby facilitate the caster to smoothly rotate the rotational axle 21 without any noise being created thereby.
